Introduction
Automated messaging through text (SMS) and instant messaging services (IMS) are low-cost solutions for patient follow-up in resource-constrained contexts. This study aims to evaluate a quality improvement (QI) initiative to improve caregiver response rates to an automated messaging system facilitating follow-up after hospital discharge of children in rural Uganda.
Methods
This initiative was implemented at Gulu Regional Referral Hospital in Northern Uganda from June 2022 to June 2024. Caregivers of children who were triaged through the Smart Triage digital platform were offered an automated follow-up program as part of routine care during this period. SMS and IMS (WhatsApp) messages prompting caregivers to report if their child had “improved” or “not improved” were sent seven days post-discharge. Non-responders and "not improved" cases were escalated to a phone call from a health worker. From April 2023 to June 2024, a QI initiative refined the messaging system to improve response rates. Data on message delivery, response rates, improvement strategies, and health outcomes were analyzed.
Results
Of 6826 participants, 6469 (95%) messages were successfully delivered. Response rates improved from 20% to 40%. In total, 1856 caregivers responded to the messages. Among the responses, 1244 (67%) of caregivers reported improvement and 612 (33%) reported no improvement. Follow-up phone calls for those “not improved” revealed 58 (9%) sought care, 12 (2%) were readmitted, and no deaths occurred. For non-responders, 206 (5%) sought care, 33 (0.7%) were readmitted, and 3 (0.07%) deaths occurred.
Discussion
Automated two-way text messages for post-discharge pediatric follow-up in Uganda yielded high delivery but moderate response rates. Iterative QI efforts increased response rates, highlighting the importance of tailored communication strategies. Automated messages can facilitate timely intervention for high-risk children and enable efficient collection of health outcomes offering a viable alternative to in-person follow-up in resource-poor settings.
